September 1998: I calculated my own "All-India"
rainfall series using data taken from the World Monthly Surface
Station Climatology and the Dai et al. gridded rainfall data set, and obtained a time series with significantly
more low-frequency variability than that exhibited by this series.

Digital values through 1997 are provided below. The
analyses have not yet been updated and only use data through 1995.

Historical record: 1871-1995

Modern record: 1950-95:

Both figures are for anomalies of June through September seasonal
totals. The mean seasonal rainfall for both the historical and modern
records is 85 cm, and the series exhibits both year to year and
decadal variability. The ordinate units are cm.

This data is provided by B. Parthasarathy of the Indian Institute of Tropical Meteorology, Pune 411 008 India. Please acknowledge Dr. Parthasarathy when using this data.

Seasonal Totals: in tenths mm
The first data value, 849.1 mm, is for 1871.

'Monthly and seasonal rainfall series for all-India
homogeneous regions and meteorological subdivisions:
1871-1994', Contributions from Indian Institute of
Tropical Meteorology, Pune-411 008, INDIA.
All India rainfall is an areal average of 29 subdivisional
rainfalls. Subdivisonal rainfalls are from areally averaged
district rainfalls. The district rainfall is computed
from averaging all stations in the district. Rainfall amounts
(in millimeters) are totals for June, July, August, and
September.
The data is consistent from 1871 - 1990 in that it is constructed
from a 306 station network, with no missing data. The number
and distribution of stations for 1991 - 1994 is unknown.
Rainfall from Parthasarathy for 1871 - 1994
1871 - 1990 from 306 stations, no missing data
1991 - 1994 station distribution unknown
1995 Preliminary rainfall values only. Station distibution
is unknown.
